Because existing sources of auto reliability information left much to be desired, in late 2005 I started conducting my own reliability research at TrueDelta.com. TrueDelta reports absolute stats like "trips to the shop" that make the differences between cars much clearer. Results are updated four times a year, so any significant changes in a model's reliability become apparent quickly.

We've been providing results for the Tucson for some time now, but more participants would still be very helpful. Especially for the 2007 and 2008.

Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, at the end of each quarter.

To encourage participation, panel members receive full access to the results for free.

We have updated results for the Tucson. In terms of successful repair trips per 100 cars per year:

2005: 28, better than average

2006: 39, better than average

2007: 46, about average, small sample size

2008, 2009: too few owners signed up

A big thanks to everyone who has been helping. We'll have further updates in May, August, and November. With more participants, we could provide more precise information and cover all model years.

We now have a separate results page for each model that includes the results for competitors. The page for the Tucson:

We have updated results for the Tucson to include owner experiences through March 2009. In terms of successful repair trips per 100 cars per year:

2007: 58, about average

2006: 53, about average

2005: 35, better than average

Very small sample size for the 2007. The other two years fell one to three responses short of the minimum for full results.

A big thank you to everyone who has been helping. We'll have further updates in August and November. With more participants, we could provide more precise information and cover all model years.

2007: 41, better than average

2005: 55, better than average

Very small sample size for the 2007. The other two years barely reached the minimum for full results.

Everyone who has been helping, thanks, I appreciate it. We'll have further updates in February and May. With more participants, we could provide more precise information and cover all model years.

130 Tucson owners now signed up, plus another 78 for the Sportage. A good start, but more are needed to provide precise results for all model years.

Hoping to also have some quick initial results for the 2010.

Just enhanced the related repair history survey so that it can (optionally) be used as a personal car maintenance record.

As always, more participants would be helpful. I'd especially like to have quick results for the new 2010.

Updated Car Reliability Survey results in May, with a preview for participants in mid-April.

We have updated results for the Tucson to include owner experiences through June 30, 2010. Other sources of car reliability information won't cover the more recent months until the summer or even fall of next year.

Repair frequencies, in terms of repair trips per 100 cars per year:

2010: 52, about average

2007: 10, better than average

2006: 71, about average

2005: 48, better than average

Small sample sizes for all but the 2005. The 2006 fell a single response short of the minimum for a full result.

Thank you, once again, to everyone who has been helping. We'll have further updates in November and February. With more participants, we could provide more precise information and cover all model years.
